Title: No sound after use Headphones
Post by: Steff260 on March 23, 2020, 05:11:20 PM

I have no sound on my laptop when playing DVD. Use VLC media player.
Sound also does not work for movies over the Internet in the Firefox browser.

Problem occurred when I wanted to watch with headphones. Headphones connected to laptop. Sound was hardly audible, even at maximum volume.  Headphones removed again. Then I wanted to continue watching the movie with laptop speakers. All of a sudden no sound anymore. Movie plays normally.

Where or what could I look up? Change which settings?

Thanks for your help

addendum

Under output device -> hardware output devices the following is displayed: no output devices available

under -> output device -> all output devices-> dummy output is displayed

Maybe this will help

Hi,

Exit all applications, open a terminal and try :
pulseaudio --kill
(or sudo pulseaudio --kill , not sure).

Then try your application again. I had trouble changing outputs in the past, if the speakers were NOT plugged in on boot time, I had no sound until this command.

Good luck!

Code: [Select]

sudo pulseaudio --kill
PulseAudio is a server. Killing it, requires Root privileges. :)
Anyway, huge thanks!
Seems I had this trouble many times, but never knew where it came from. I'll test this if I get the annoying "blank sound" again.
Unfortunately, I could never spot "the perpetrator"...
Could be anything: Audacity, OpenShot, VLC or whatever uses a sound playing line of code.

The Thread-Time-Machine strikes again! ;)
No problem!
You can also choose your output audio device in the volume controls.
For me, it was usually that the audio switched to HDMI-audio but there was no speakers on my HDMI monitor. ;)
